Then lets add Chubby Checker, Elvis and Chuck Berry, they have more influence in Progressive ROCK than A Kind of Blue, and if we want to go back, then add Mussorgsky, Bach, etc.There is a limit I believe.Iv???nMight as well add James Brown, Sly and the Family Stone, and Karlheinz Stockhausen to this site, as he is who was influencing Miles Davis during the making of his late-60s and 70s albums.J
